MACHINE FOR MAKING METAL TUBES.

Application filed Mays, 1911. I Serial No. 626,104.

To all whom it may concern:

Be it known that I, GEORGE W. BEADLE, a citizen of the United States, residing at Bayonne,in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Machines for Making Met-a1 Tubes; and I do hereby declare the following to be a full, clear,-and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

ThlS invention relates to machines for making spirally wound tubing, and has for its object to produce a mechanism for manu fact-uring such tubing out of a single strip of material and at the same time effectually closing the seams between contiguous edges of the strip.

With these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims. I

Referring to the accompanying drawings forming a part of this specification in which one form of my invention is illustrated, and in which like numerals designate like parts in all the views :Figure 1 is a plan view of a complete machine for making spiral metal tubing; Fig. 2 is an end elevation of the parts shown in Fig. 1 looking inthe di- 7 ports.

rectlon of movement of the arrow on the,

strip; Fig. 3 is a side elevation of the machine, showing the mandrel in section; Fig. 4 is a longitudinal sectional view on the line 44 of Fig. 1.; Fig. 5 is a detail perspective view of the tube strip partially wound; Fig. 6 is a transverse sectlonal view of the finished tubing; and Fig. 7 isa detail view of the crimping rollers and their sup- 1 designates a base suitably supported by l the legs 2, and on said base aremounted the standards 302 and 303 co-acting with a.

four standards 300, 301, 302 and 303 and which have suitably journaled therein a drivin shaft 5 and a driven shaft 6 as best shown in ig. 2. The shaft'5 has at one end a fixed pulley 7 and a loose-pulley 8 adapted to be driven by a belt in the usual manner, and the driving connection between the shafts consists of a pair of meshing pinions 9 and 10 mounted respectivelv on said shafts.

A roller 11, mounted on the shaft 5 between means for feeding the strip A; and cooperating with said feeding rollers are two diagonall'y disposed flanging rollers 130 and 131 journaled in arms 14 on said standards,

and which in connection with the feeding rollers form flanges B and C upon the side edges of the moving strip A. The purpose of-disposing the flanging rollers 130 and 131 in opposed diagonal relation is to turn the flanges to opposite sides of the strip.- seejFig. 5, in order to form the interlocking seams like roller 12"011 the-shaft 6 constitutes a shown in Fig. 6. After its treatment by the flanging rollers the moving stri is next subjected to the action of a pair 0 crimping or of a chain 160 riding on sprockets 170 that I are carried by the lower ends of the roller spindles 150 (see Fig. 7).

After having been subjected to the action of the spinning rollers 15 the strip A passes forward to and is wound on a mandrel 18, which is mounted diagonally with respect to the machine in suitable standards 19, only one of which is shown. 'Said mandrel is also provided with a spiral groove or channe120 for the reception of the crimped edges of the strip which, as illustrated, are formed internally of" the tube. mandrel 18 the finished crimped edges B and O are united and the joint sealedthrough the action of an ironing or pressing roller 21 which is mounted on a shaft 22 journaled within suitable bearings on the standards 23. The-rotation of the roller 21 is effected through a gearing connection with the shaft 5 comprising a sprocket chain 24-, traveling over sprockets 25 and 26 mounted on said shafts 22 and 5 respectively. A belt 27 run- ;ning onpulleys 28 and 29, fixed on spindles 280 and 290 ournaled-in the yoke frames 30 and 31 passes around the formed tube and feeds it along" the length of the mandrel.

The means for imparting movement to the belt supporting pulleys 28 and 29 consists In passing to the of 'a relatively short shaft32 journaled in the standard 33 and having cone pinions 34 and 35, the latter of which meshes with and is driven by a cone inion 36 carried by the shaft 6 (see Fig.2 The cone pinion 34 meshes with a bevel gear 37 that is fixed to the pulley spindle 280. From thegear Wheel .37 there is a positive drive between the two belt pulleys (see Fig. 3) consisting? of a bevel gear 38 fixed to a shaft 39 w ch is journaled within the supporting. frame 31 and a standard 40. The shaft 39 has a pmion 41 in mesh with a like pinion 42 on a' oountersshaft 43, carrying apinion 44 meshing with a pinion 45 on the shaft 46. The

shaft 46 is journaled in the upright 47 and frame 30-and has a bevel pinion 48 meshing with a bevel-pinion 49 on the belt pulley shaft 290. The driven shaft 32-also e'flects the driving of the crimping rollers 15 through the medium of the chain 160 that 1 runs on a sprocket 50 on the shaft 280, (see Fig. 3)

The operation will be clear from theforegoing, but maybe briefly summarized as ollows:A suitable stri A of sheet ,material, preferably tinned 1ron is fed by the rollers 11 and 12 between the rollers 130 and 131 which serve to turn over the edges B C of said strip in opposite directions. These edges are next passed between the finlshlng rollers 15 which serve to properly shape them so as to enable them later to form an interlocking seam, and the strip A is further fed between the compressing roller 21 and the mandrel 18. The mandrel '18 is provided with a groove 20 which receives the seam formed on the interior of the finishedtube and as it revolves the strip A is spirally wound on said mandrel while the:

upturned edge B of one winding interlocks with the downwardly turned edge. (1 of a It lS .'Ol)VlO11S that those skilled succeeding winding. 1 The compressing roller 21 in the 'meantimefirmly resses the flanges B and C' of succeeding windings together and thereby forms 'a sealed seam in the finished tube. The belt 27 serves to feed the tube along themandrel, and after it asses off thesame the'said tube may be cut mto suitable. lengths by mechanism not shown, preparatory to the manufacture of containmg vessels out of the same. 4

p in the art may vary the details 'of construction and arrangement of parts without departing from the spirit of myinvention, and therefore I do not wish to be limited to such features except as may be required. by theclaims.

In a tubeforming machine the combination of means for feeding a strip out of which the tube is to be formed; means for turnin over the edges of said stri additional means for crimping and ishing said turned over edges; a mandrel around which said strip may be spirally wound; and'a roller for pressingdown said turned over edges, substantially as described.
